As a network engineer you are required to design, implement and test the given network diagram in a simulation environment for testing before the real implementation for one of the customers. Use IP addresses given below.

For LANs IPv$4=10\mathrm{.}0\mathrm{.}0\mathrm{.}0/16,$ use VLSM to assign a suitable IP address to meet the following requirements.

$1.$ Branch$\_1$:

$$ LAN A: $60$ hosts

$$ LAN B: $120$ host

$2.$ Branch$\_2$:

$$ LAN E: $250$ hosts

$3.$ Branch$\_3$:

$$ LAN C: $10$ hosts

$$ LAN D: $20$ hosts

Part $1$: Basic Configuration $($Configure the passwords at the end$)$

$$ Disable DNS lookup in all routers.

$$ Configure device name as shown in the topology$/$Tables$.$

$$ Assign $$enPa$$$2$ as the privileged EXEC secret password.

$$ Assign $$vtyPa$$$2$ as the vty $04$ password.

$$ Assign $$conPa$$$2$ as the console password.

$$ Configure a MOTD banner to warn users that $$unauthorized access is prohibited$.$

Part $2$: IPv$4$ configuration

$$ Configure all routers interfaces using IPv$4$ addressing table.

$$ Test and troubleshoot the configuration using ping between all directly connected devices.

Part $3$: IPv$6$ configuration
